Meter decay shapes how quickly level information disappears from the display.
Meter decay is the speed at which a meter falls after the signal gets quieter. Fast decay shows short changes quickly, while slow decay makes level movement easier to read.
Different meter types use different ballistics because they are built to answer different questions.
A peak meter with fast decay can reveal transient spikes. A VU-style meter moves more slowly and gives a clearer sense of average musical level.
If you misread the decay behavior, you may mistake a display style for a real level problem.
Use peak and true-peak meters for overload risk, loudness meters for delivery level, and slower average meters for musical balance.
Meter Core groups complementary readings so meter movement has context instead of becoming a single misleading number.
